Thank you of your purchase from etrailer of the Curt Echo Brake Controller # C51180, and we can try to figure out what's happening here. The blue light on means there is not a trailer connected, and if this is happening and the brakes are locking up, there are a couple probable issues.

The first is to check for any type of corrosion on the connectors; it can hamper the signals getting through and cause a "no trailer connected" problem so look for that. If that's not the issue it could be a short in the wiring, so you will need to check the wiring on your trailer and see if there is a broken, crimped, or otherwise damaged wire that is causing the short, which you can repair with 10 gauge wire # 10-1-1.

Finally, you'll want to visually inspect the brake magnets; if you can see the copper windings coming through the magnets will need to be replaced. To test the magnets use a multimeter and follow the help article I have linked to guide you on testing magnets, as bad magnets can also cause the issue.
